摘要： Systems and methods for controlling camera settings of a camera to improve detection of faces in an uncontrolled environment are described. A first image is received from the camera, where the first image is captured by the camera at a first set of camera settings. A face is detected in the first image. The camera is adjusted to a second set of camera settings based on the detected face, where the second set of camera settings different from the first set of camera settings. A second image is received from the camera, where the second image is captured by the camera at the second set of camera settings. The face is detected in the second image. A quality metric of the face in the second image is determined where the quality metric is indicative of an image quality of the face in the second image. The camera is adjusted to a new set of camera settings to increase the quality metric of the face in subsequent images, the new set of camera settings different from both the first set of camera settings and the second set of camera settings. Once a sufficient quality metric of the face is achieved, the face is acquired, or otherwise captured, by the camera or other sensors.
摘要翻译：描述了用于控制相机的相机设置以改善在不受控制的环境中的面部的检测的系统和方法。从相机接收第一图像，其中在第一组相机设置下第一图像被相机捕获。在第一张图像中检测到一张脸。基于检测到的脸部将相机调整到第二组相机设置，其中第二组相机设置与第一组相机设置不同。从相机接收第二个图像，其中在第二组相机设置下相机拍摄第二张图像。在第二张图像中检测到脸部。确定质量度量指示第二图像中的脸部的图像质量的第二图像中的面部的质量度量。相机被调整到一组新的相机设置，以增加后续图像中的脸部的质量指标，新的相机设置集与第一组相机设置和第二组相机设置不同。一旦实现了面部的足够的质量度量，则通过相机或其他传感器获取或以其他方式捕获面部。

摘要： Various implementations of the invention perform facial recognition on a target image compared against a color image from an image gallery, where the target image was acquired by an infrared-sensitive camera of a target that was illuminated with infrared light. According to various implementations of the invention, a blue component and a green component of the pixels in the color image are suppressed or eliminated, and facial recognition is performed between the target image and the color-suppressed image.

摘要： A system and method for improving a video characteristic of a video stream is described. According to various implementations of the invention, a changed region between a later-in-time image frame and an earlier-in-time image frame and an unchanged region between such two image frames are determined. A new improvement to the video characteristic is determined and applied to the changed region of the later-in-time image frame. A prior improvement to the video characteristic that was determined for the earlier-in-time image frame is applied to the unchanged region of the later-in-time image frame.
